I recently built an eggbot using the files and links provided in this thing. For a couple of days, it worked outstanding. It moved with precision and accuracy, and I was able to create some impressive egg prints.
Now however, the pen stepper motor that controls left/right movements has began acting strangely. It moves inconsistently and often doesn't have enough power to move back and forth. I have tried replacing the motor, driver, and arduino- still weird motor activity. Does anyone have any suggestions?
Thanks,
